Condenser, and high-and-low-beam integrated vehicle lamp module

A condenser, comprising at least one light incident portion, a light passage portion, and a light emergent portion, wherein a 50L dark area light shape forming structure is formed on the light passage portion;

• the 50L dark area light shape forming structure protrudes from a surface of the light passage portion and has a slope surface, and the 50L dark area light shape forming structure further has a top surface, a bottom surface, and two side surfaces on the side of the slope surface, wherein the top surface and the bottom surface are two substantially parallel planes;
• and a distance from the slope surface to the surface of the light passage portion gradually increases from a position close to the light incident portion to a position close to the light emergent portion, wherein an edge of the light emergent portion forms a cut-off line forming structure, and an edge line of the light emergent surface of the 50L dark area light shape forming structure is in connection with an edge line of the cut-off line forming structure;
• and wherein the slope surface and a surface of the light passage portion where the slope surface is located form an included angle α, wherein 0°<α≤10°.
